Procedure: diag_p, p, n, t=t, s=s INPUT: p: pressure array of n by 6 or a string (e.g., 'p_3d_el') n: density array of n or a string (e.g., 'n_3d_el') PURPOSE: Returns the temperature: [Tpara,Tperp,Tperp], and the unit symmetry axis s. Also returns 'T_diag' and 'S.axis' for plotting purposes. CREATED BY: Tai Phan 95-09-28 LAST MODIFICATION: 95-9-29 Tai Phan
